Forge-pibe



'UNITED STATES PATENT OFFICE.

WM. RODGERS AND ABRAHAM' BANNON, OF BELLEFONTE, PENNSYLVANIA.

FORGE-FIRE.

Specification of Letters Patent No. 14,575, dated April 1, 18:56.

To all whom it may oonoern Be it known that we, VVILLIAM RoDGERs and ABRAHAM BANNON, of the borough of Bellefonte, in the county of Center and State of Pennsylvania, have invented an Improvement on the Forge-Fire; and we do hereby declare'that the following is a full and exact description thereof, reference being had to the aceompanying drawings and to the letters of reference marked thereon.

The nature of our inventio-n is to add to the common forge fire an additional twyer on the opposite side of the fire by which we have a blast playing on the loop o-r iron in the fire from both sides at the same time thereby lessening the time of making a loop fully onethird and increasing the quality of the iron from one-third to onehalf; by the old process of the single blast the end of the loop or iron on which the blast played was good while the other end was defectiveand if the iron Was intended for any particular use it was usual to reject from one-fourth to one-third of the loop. But by our process the whole loop is made good and all of it fit for any purpose.

By our process we save fully one-third of the fuel that was consumed in the old way. A part of our invention consists in the shape of the bottom of the fire; in place of making the bottom level or flat as in the old way we diverge from a straight line an inch more or less as may be required to the center of the hearth from each side so as to form a kind of concave bottom the cinder naturally flowng off at a hole in the center of the hearth left for that purpose.

To enable others skilled in the art to make and use our invention we will proceed to describe its Construction and operation.

Te construct our forge fire on the plan of the common charco al Pennsylvania forge fire and to that fire We add an additional twyer on the opposite side of the fire A o-n the draft. This twyer is constructed precisely like the other except that it is made to move back by a lever marked B on the draft in order to be out of the road in taking the loop or iron out of the fire. The twyer is constructed larger or smaller so as to aclmt the exact quantity of blast required by the operation. The fire or hearth is also constructed on the old plan except the bottom of the fire or hearth marked C on the draft which is constrncted by diverging from a straight line from both sides to the center of the hearth about one inch more or less forming an angle in a concave direction. A forge so constructed will do one third more work with one-third less fuel and Will make a quality of iron from onethird to one-half better than the old plan.

What we claim as our invention is- The forge hearth C, as described when employed in connection with the twyers D and A operated by the lever B, the whole arranged and eonstructed in the manner herein set forth.
